Serum elastase levels following a stroke in elderly subjects.

Numai utilizatorii înregistrați pot traduce articole

The elastase content of the serum of stroke patients is appreciably higher immediately after the cerebral incident and, in the case of those destined to survive, falls subsequently back to the normal level for their age group. The degree of elevation of the elastase content, the period which elapses

Polymorphonuclear leukocyte elastase in patients with stroke.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Polymorphonuclear leukocytes (PMNL) are involved in the pathogenesis of acute cerebral ischemia and atherosclerosis. Elastase is one of the proteolytic enzymes released by activated PMNL. We evaluated whether plasma levels of elastase-inhibitor complexes (EIC) are related to acute cerebral

Strongly increased levels of fibrinogen elastase degradation products in patients with ischemic stroke.

Numai utilizatorii înregistrați pot traduce articole

Ischemic stroke is associated with leucocyte activation. Activated leucocytes release elastase, an enzyme that can degrade fibrinogen. Fibrinogen elastase degradation products (FgEDP) may serve as a specific marker of elastase proteolytic activity. In a case-control study of 111 ischemic stroke

Evaluation of granulocyte elastase as a sensitive diagnostic parameter of inflammation in first ischemic stroke.

Numai utilizatorii înregistrați pot traduce articole

Several traditional vascular risk factors are associated with proinflammatory alterations, including leukocyte activation, and predispose cerebral vasculature to thrombogenesis on inflammatory stimulation. PMN elastase derived from the activated neutrophils might play an important role in injury.

Neutrophil elastase and neurovascular injury following focal stroke and reperfusion.

Numai utilizatorii înregistrați pot traduce articole

Neutrophil elastase (NE) degrades basal lamina and extracellular matrix molecules, and recruits leukocytes during inflammation; however, a basic understanding of the role of NE in stroke pathology is lacking. We measured an increased number of extravascular NE-positive cells, as well as increased

Dissociation of elastin and elastase-like activity of aorta from stroke in stroke-prone SHR.

Serum elastase activity, serum elastase inhibitors, and occurrence of carotid atherosclerotic plaques: the Etude sur le Vieillissement Artériel (EVA) study.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND In the last decades, interest has increased in the potential deleterious atherogenic effects of some cellular elastase activities. The results of experimental and clinical investigations were inconsistent. In this report, we assessed the associations of serum elastase activity and serum

Elastin and elastase-like enzyme change in aorta of rat with malignant hypertension.

Numai utilizatorii înregistrați pot traduce articole

In order to study the role of elastin in arteries with respect to hypertension and hypertensive arterial disease, aortic elastin content and elastase-like enzyme activity were examined and compared in stroke-prone spontaneously hypertensive rats (SHRSP), which show malignant hypertension, and

Increase in jugular levels of polymorphonuclear neutrophil elastase in patients with acute cerebral infarction.

Numai utilizatorii înregistrați pot traduce articole

To elucidate the involvement of activated polymorphonuclear neutrophil (PMN) proteolytic activity in the pathophysiology of cerebrovascular stroke, we measured internal jugular venous and femoral arterial levels of PMN elastase in 6 patients with acute stroke from the day onset (day 0) to 7 days

Related age changes in the elastase and lipid contents of normal and hemiplegic subjects of various ages.

Numai utilizatorii înregistrați pot traduce articole

Elastase and lipid levels of the plasmas of subjects and of those who have suffered a stroke have been measured, and it has been shown that the normal age related fall in elastase content is mirrored more closely by the fall in high density lipoprotein cholesterol than by changes in total

Serum elastase activity is elevated in migraine.

Numai utilizatorii înregistrați pot traduce articole

Migraine has been associated with diseases considered to be related to extracellular matrix disorders--in particular, cervical artery dissection. In this population-based study, we found a highly significant association between migraine and the activity of serum elastase, a metalloendopeptidase

Calcium-dependent bidirectional power stroke of the dynein arms in sea urchin sperm axonemes.

Numai utilizatorii înregistrați pot traduce articole

Active sliding between doublet microtubules of sea urchin sperm axonemes that were demembranated with Triton X-100 in the presence or absence of calcium was induced with ATP and elastase at various concentrations of Ca2+ to examine the effects of Ca2+ on the direction of the power stroke of the

Complications of elastase-induced arterial saccular aneurysm in rabbits: case reports and literature review.

Numai utilizatorii înregistrați pot traduce articole

Endoluminal infusion and incubation of elastase with or without collagenase into the rabbit common carotid artery is an established model of arterial saccular aneurysm. The model mimics naturally occurring human cerebral aneurysms in many ways, including histologic and morphologic characteristics,

[Computer tomographic and laboratory predictors of clinical outcomes of acute ischemic stroke patients after the systemic thrombolytic therapy].

Numai utilizatorii înregistrați pot traduce articole

Today the systemic thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA) is the most effective treatment of ischemic stroke. We included 116 patients with stroke, 82 received rt-PA, 34 were enrolled to the control group. Median NIHSS score was 16,2 +/- 5,4 in the main group and

Correlation between angiographic and particle image velocimetry quantifications of flow diverters in an in vitro model of elastase-induced rabbit aneurysms.

Numai utilizatorii înregistrați pot traduce articole

The rupture of a cerebral aneurysm can result in a hemorrhagic stroke. A flow diverter, which is a porous tubular mesh, can be placed across the neck of a cerebral aneurysm to induce the cessation of flow and initiate the formation of an intra-aneurysmal thrombus. By finding a correlation between
